Shell medium, slender, light corneous. Lower whorls smooth, flattened, nearly of the same width. Upper whorls indistinctly wrinkled-costate. Neck strongly wrinkled-costate. Peristome with simple margin. Lamellae superior and spiralis overlap. In front view lamella subcolumellaris often visible. Lunella lateral, mostly connected to the basalis. Subclaustralis as long as the basalis, sulcalis present. Anterior plica superior absent or very weak and separate from the lunella complex. Dimensions (in mm). Hs: 15.6-18.6 (holotype 18.6), Ws: 3.8-4.2 (holotype 4.2) ( Nordsieck 1972 , 1977 ). Type locality. Macedonia, gorge of the Radika near Debar, 1.5 km upstream of the bridge. Type material. Type locality, leg. Nordsieck, 28.viii.1971, holotype (SMF 221318), paratypes (SMNS-N 5509, ZMH 91590/8); Radika gorge above Nicpur junction, leg. Nordsieck, 5.viii.1974, paratype status doubtful (SMNS-N 6933, SMF 247211/5). Other material. Macedonia, Gostivar District, upper valley of the Radika, 6 km from the Debar to Gostivar road toward Nicpur , 1100 m, 41.7655°N , 20.6666°E , leg. ZF, EH, KJ, HS, 14.x.2014 (NHMW 110430/MN/0108); Mavrovo District, Radika Valley, along the Debar to Gostivar road at the Nicpur junction, 930 m, 41.7203°N , 20.6682°E , leg. ZF, EH, KJ, HS, 14.x.2014 (NHMW 110430/MN/0107); same locality, leg. ZE, ZF, AH, 8.iv.2004 (HNHM 94919); 500 m E of the Nistrovo junction along the Debar to Gostivar road, 900 m, 41.7102°N , 20.6564°E , leg. ZF, EH, KJ, HS, 14.x.2014 (NHMW 110430/MN/0109); at the Nistrovo junction, 890 m, 41.7079°N , 20.6500°E , leg. ZF, EH, KJ, HS, 14.x.2014 (NHMW 110430/MN/0110); same locality, leg. ZE, ZF, AH, 8.iv.2004 (HNHM 94918). Distribution. Valley of the Radika in western Macedonia. This taxon is known to occur within a few km section of the valley. Downstream it is replaced by Montenegrina perstriata radikae (Fig. 25). Remarks. In the description, Nordsieck (1972) mentions material from from three sites, without specifying which of these are designated as paratypes. Sample SMF 247211 is labelled as paratypes and Zilch (1981) lists it accordingly. But SMNS-N 6933, the other part of the same lot, is without indication of type status.
